PABNT COMPOSlTION.

SPECIFICATION forming part of Letters Patent No. 325,160, dated August25, 1885.

(Specimens) To all whom it may concern.-

Be it known that I, PLATT O. CONNELL, of Chicago, in the county of Cookand State of Illinois, have invented a new and useful Oomposition ofMatter to be Used as a Transparent Paint, and is especially adapted as acoating for walnut or walnut-stained woods, to give to such wood animproved shade of color imitating the color produced by age, of whichthe following is a specification.

The transparency of the compound permits the fine grain of the wood tobe clearly visible through the coating, and unseasoned wood of ordinaryquality so coated closely rtsembles fine grades of wellseasoned antiquewalnut.

My invention consists in the employment of substitute or oil shellac asa body for the coloring material, and the composition prefcrablyemployed to imitate the color of antique walnut consists of thefollowing ingredients, in the proportions stated: substitute or oilshellac, five gallons; coloring material, one gallon. The coloringmaterial to imitate antique walnut is composed of Vandyke brown, fourparts; rose-pink, one part, and a sufficient quantity of turpentine tomake a liquid of the coloring material. Substitute or oil shellac is awell-known article of commerce, and consists of a gum, an oil, and adrier, African gum, linseedoil, and japan being preferably employed,with turpentine to thin it down.

The proportions may be varied materially to secure the desired fluidity,consistence, and drying qualities to suit the nature of the material tobe coated.

The coloring material employed must be ground in japan when a quickdrier is required; but oil colors may be employed, if preferred.

The turpentine and coloring-matter are first mixed thoroughly togetheruntil a liquid solution is obtained, which solution is after ward mixedwith substitute or oil shellac in about the proportions stated.

The color must be applied with asoft brushsuch as a fitch or badgerbrush.-as a smooth, unstreaked coating of the color cannot be laid witha coarse or bristle brush. The pores of the wood are first well filledbefore putting on the color, and the coloris then varnished over in theusual way.

\Vhen the color is employed over the tiller,

varnish which is applied over the color from sinking into the wood, thusserving the double purpose of a shellac and a coloring material.

The rose-pink has a tendency to give to the Vandyke brown that richreddishbrown cast which is characteristic of old or antique walnut. Anystained wood in imitation of walnut may be coated with the coloringmaterial above described, and the antique color will be given to thesurface so covered.

The transparency of the coloring material, as above stated, permits thefinest-grained portions of the wood to be seen, and a finer quality ofwalnut is apparentthan can be obtained by any of the ordinary methods ormeans heretofore employed for coating or surfacing walnut.

Substitute or oil shellac has been heretofore used as a cheapercomposition than the ordinary or alcoholic shellac previously employed;but, so far as I am aware, substitute or oil shellac has not beenemployed heretofore as a body for coloring material.

Other coloringmatter than that above named may be employed to producethe required shade or color, and diiierent proportions ofcoloring-matter and substitute or oil shellac than those above given maybe employed. Turkey umber may be substituted for Vandyke brown, androselake may be substituted for rose-pink, without departing from myinvention, as a color somewhat similar to that required, but not sogood, may be thus obtained without departing from my invention, as theessential feature of my invention consists in the employment ofsubstitute or oil shellac as a body for the coloring material.

I claim as my invention and desire to secure by Letters Patent- Thecoloring composition for imitating the color of antique walnut,consisting of substitute or oil shellac, Vandyke brown, and rosepink,substantially as herein described.
